Final Mining Reclaimed Slope:3H:1V <br /> Slope:2H:1V Slope <br /> Created by Dozer <br /> Push Active Mining <br /> Highwall(Near <br /> , Vertical) <br /> Figure D-1. Highwall Slopes <br /> Mining is broken up into pods. Pod 1, the east area, will be mined out first. West Pod, the west <br /> area, will be mined out second. See Map C-2 for locations of each pod. Both pods are <br /> connected by an internal haul road. Reclamation will be completed as soon as possible as <br /> mining progresses. This means that any slope or area where mining is completed will be <br /> backfilled, topsoiled, disced and seeded. Once mining begins in a new pod, the remaining areas <br /> in the previous pod will be reclaimed. This reduces the overall disturbance at any point in time. <br /> There is sufficient topsoil and overburden on site to successfully reclaim the site to its final <br /> condition. Reclamation includes regrading of the site, topsoiling, and revegetation to create a <br /> final land use of rangeland. <br /> The total disturbance area at the Lockhart Pit will be no more than 10 acres of mining area. The <br /> maximum ongoing disturbance area, which is the area that is active for operations but not yet <br /> reclaimed, will be 10 acres. <br /> Dewatering will not be required while mining as groundwater is not anticipated to be exposed. <br /> No groundwater was encountered during exploration. The nearest existing well (290960-) is <br /> installed with a collar that is below the bottom of mining (see Map C-2). Therefore, it is assumed <br /> to be abandoned. The groundwater table is at an elevation of roughly 7300', clearly well below <br /> the lowest elevation of mining. If any groundwater is exposed, mining will cease, and the mining <br /> depth will be adjusted to two feet above the groundwater level. <br /> No blasting will take place at Lockhart Pit. No refuse, acid, or toxic producing material are <br /> expected to be encountered in this operation. If these materials are encountered, at least two <br /> feet of inert material will be placed over the area and mining will move to a different area. <br /> Lockhart Pit <br /> March 2024 D-2 Lewicki 81 Associates <br />
